severing portions of a substance from the main body thereof, in the formof extremely thin flakes.

\Ve accomplish this purpose by means of a sheet metal body having asubstantially fiat surface and provided in said surface with a series ofslits, said slits arranged in lines inclined to the longitudinalextension of the body and also so that the several lines of slits on oneside of the medial line of said body converge toward corresponding linesof slits on the other side of said medial line. These slits are soformed that one side wall or margin of each slit is raised above theopposite side wall of said slit and the raised side wall is preferablyprovided with an angular formation or somewhat sharpened cutting edge.

Referring to the drawings, which illustrate merely by way of examplesuitable means for the embodiment of our invention:-

Fig. l is a plan View.

Fig. 2 is a side elevation.

Fig. 3 is a section on a. greatly enlarged scale, on line 3-3 of Fig. 1.

Fig. 4 is a similar section on line 3-3 of Fig. 1.

Similar numerals -refer to similar parts throughout the several views.

In the example shown in the drawings, the sheet metal body 5 is mountedon the frame 6 having suitable supports 7 and 8, one at each end. Onesupport, for example 7, is adapted to rest upon a table or othermaterial receiving structure while the other support 8 serves as ahandle to be grasped by the operator.

As a preferable construction we have shown the support 7 provided withhook shaped formations for engaging the mar gins of a receptacle wallsuch as a sinkor tub.

The body portion 5 is provided with a series of slits 9 extendingthrough the same. These slits 9 are very narrow, elongated openingshaving one long margin 10 raised above the opposite long margin 11 andabove the plane of the surface of the sheet 2 metal body 5. These slits9 are all arranged diagonally or inclined to the longitudinal extensionof body 5. i i

' Drawing an imaginary medial line longitudinally upon said body 5, itwill be noted that the lines of slits'on each side of said medial lineconverge toward .each other as shown in Fig. 2, and that alternate linesof slits on either side of the medial, line slightly overlap each otherand said medial line.

It will also be noted that/these inclined slits 9 are staggered as tolines parallel with said medial line.

It will also be noted that when striking up one longitudinal margin 10above the other margin 11 of each slit, the elevated edge is sharpenedor of angular formation as shown in Figs. 3 and i to facilitate in theoperation to be described. This may be secured for example by takingadvantage of the thickness of the sheet metal and slightly turning oneedge or corner further out than the other, as shown in Fig. 3, or thethickness of said margin may be reduced in any suitable way.

In operation the device is supported by the supporting part 7 resting,for example, upon a table or other supporting surface, while the part 8is held in the hand of the operator. The substance to be flaked, such asa cake of soap, is rubbed over the surface of body 5, so that when movedin direction of the arrow Fig. 2, the substance engages with the cuttingraised margins 10 of the slits 9 and, due to the fact that the saidslits 9 are inclined to the lines of movement of the substance operatedupon, and the cutting margins 10 correspondingly inclined, there is ashearing action of said cutting edges upon the substance, with theresult that very thin flat flakes or shavings are severed from saidcake. of soap, for example, which flakes are carried through said slit-s9 and deposited beneath the same. The arrangement of the lines of slits,as above de scribed, that is, with all the lines of slits on one side ofan imaginary medial line, converging toward corresponding lines on theother side, serves to keep the object operated upon, as it is rubbedover the surface of bod 5, moving substantially along said medial line,so that the maximum efiiciency is secured for all the severing edges ormargins of the several slits.

What we claim is 1. In a device of the character describedasheet metalbody provided with lines of separated slits inclined to the longitudinalextension of the body ,each line com rising a plurality of said slitsformed 'eac with one of its long margins raised above the oppositemargin. V

2. In a device of the character described a sheet metal body providedwith lines of short separated slits inclined to the longitudinalextension of the body, each line comprising a plurality of said slitsformed each withone of its long margins raised above the oppositemargin, said raised margin having a sharpened engaging edge. l

In a device of the character described a sheetmetal body provided with a.series of slits arranged in lines inclined to the longitudin alextension of the body and also so that the several lines of slits on oneside of the medialline of said bodyconverge toward corresponding linesof slits on the other side of said medial line, said-slits formed eachwith one of its long margins raised above the opposite margin.

4. In a device of the character described a sheet metal body providedwith a series the medial lineof said body convergetoward Vcorresponding. and slightly overlapping in alternate order lines ofslits on the other side of said medial line said slits formed each wlthone of its long margins raised above the opposite margin.
